I think I have failed to understand the above.

Does the Emacs integrated CEDET no longer use mode-local to call
semantic-new-buffer-fcn?  That could be good news.  The hooks available
in Emacs to detect a change in major mode for mode-local.el have been
challenging to get right, and I think they can still sometimes not work
right.

I did fail to explain in my paragraph above that mode-local.el would
need to be active for any files to be parse-able.  I was referring to
semanticdb, and semantic-idle features do not need to be enabled for
SRecode to be able to parse/compile template files.  As you point out,
the semantic-new-buffer-fcn does need to run, and the mode-local
settings need to be active for semantic to parse stuff.

Is there a desire to have srecode parse/compile template files while
leaving mode-local inactive?  Does mode-local get activated with
semantic-mode?  Perhaps I should check out a fresh copy of 
Emacs to better understand.  I've been worried of doing so because I
know I'll then need to also figure out how to enable my CEDET distro
shadowing the Emacs version, and I don't really want to do that work.
