I don't particularly agree with this. The code is there, it's not restricted to only use by templates, nor was it meant to, IMO. If it were, it would be part of a template helper file somewhere, which it isn't.

So now I'm totally confused!! Should it be moved to the template helper then? Which file is the template helper?

@laoneo I believe what @dongilbert Is saying is that this function is not restricted to only templates.

According to bakual and david they are...

I think a more accurate conclusion from that discussion would be that while any extension can load Bootstrap, even via this function, it should be left to the template to do.

What @dongilbert stated in his first response, if this function was restricted to only the template, the function would exist only in the template helper.

Who are bakual and david to state the purpose of the method? They didn't issue the Pull Requests that put the code into Joomla; I don't think they can speak towards the original intent.

(Nothing against you guys, I do appreciate your contributions on the mailing list.)

The way I see it, the thread on the mailing list was geared more toward discussing best practices than anything else.

Some people say this some that. Then close this pull request and I will go my way...Just thought it would clear things up as the conclusion of the mailing list thread was that the loadCss function should only be called from a template. Who has then the final decision to make and define the way to go?

We don't have the means to enforce this within the code, all we can do is call it best practice. So maybe the doc block should reflect that it's recommended that the method is only used within templates, and extended documentation (i.e. the docs wiki or when we get the API site updated) can further explain the rationale for this thinking.
