[#30272] - Joomla 4 template namespace and template custom form fields

Problem identified
Initially I've posted a question on joomla.stackexchange.com, but I think it would be better to report the issue right here.
It seems addfieldprefix isn't working with Joomla 4 SITE templates, also there is no documentation, resource or any information on using namespaces with Joomla 4 templates.
So far, namespaced plugins seem to work fine when re-using custom form fields from plugin to plugin, but a template cannot do that with it's own custom fields or namespaced plugin form fields.
Even if we were to implement something like a library, we would still not be able to use them with templates.
Proposed solution
Probably editing Joomla/libraries/namespacemap.php to include template and enable the ability to add <namespace>Joomla\CMS\Template\TemplateName</namespace> in the templateDetails.xml file.
Open questions
- Is this something that's not implemented yet, or is there a plan to implement namespace and a usable replacement for
addfieldpathwithaddfieldprefixto work with templates? We can use the namespace to extend a template namespace with something useful like aTemplateHelperfor various capabilities. - In terms of templates, are the
addfieldpathandaddfieldprefixattributes both going to be supported in Joomla 4+?

Copy from my templateDetails.xml
addfieldprefix="Joomla\CMS\Plugin\EditorsXtd\Vimeo\Field"
I misspelled here only, will correct the above.
Yes there's no real concept of namespaced resources for templates. However you can still use addFieldPath and addFieldPrefix from J3. Although I'm not against introducing the concept of a namespaced autoloaded area for templates either.

My concerns:
- when
addfieldpathis going to be deprecated, gonna be a nightmare to update 10+ templates - since
addfieldpathis not working with form fields defined in namespacedplugins/pluginTYPE/pluginName/Fieldplugin folder (I tested as writing here), I would have to do something likeplugins/pluginTYPE/pluginName/fieldsLegacyforaddfieldpath, but why would we have to do that?
so if you're using formfields in the plugins directory then you need to use the addfieldprefix and that should work just fine in j4. i assumed you were talking about form fields within the template itself (which of course wouldn't be autoloaded). Using a combination of addfieldpath and addfieldprefix should be fine too.

No, I said I wanna use form fileds from my plugins directory in the template form via addfieldprefix.

Also this should work with addfieldprefix currently loading only via addfieldpath and the old "namespace".
So, we need to make custom form fields to autoload via addfieldprefix in template forms.

That should work fine - we'll need to spend some time figuring out what doesn't work exactly here. The plugins if you've defined the namespace section should be autoloaded just fine.
I'm talking with my files in front of me, it doesn't work and you're talking "should".
@wilsonge after a while I realize I was replying here with a little bit of pressure, my apologies.
I had a type error addfieldprefix="Joomla\CMS\Plugin\EditorsXtd\Vimeo\Field" should have been addfieldprefix="Joomla\Plugin\EditorsXtd\Vimeo\Field", this works in templateDetails.xml (facepalm).
I have good news, I've implemented namespace templates with #30816, please test and report back any suggestion or idea.
Thanks and good day.

Not an answer. I don't know. But
Is it just a typo inside this issue?
addfieldpreffix(2 f)versus
addfieldprefix
