bug#57003: 28.1.90; Can local variables be loaded before loading major mode?

[Ihor Radchenko]

Hi,

Some user settings in Org mode need to be set before loading the major mode.
Further, some people want to set such settings in individual files using 
file-local variables.

However, Emacs loads file-local variables only _after_ major mode is being 
loaded.
As a result, we are getting user requests like

Currently, Elisp allows manual loading of file-local variables via 
`hack-local-variables'. However, this function itself is too forceful, and it 
is running, e.g. in non-file buffers. Moreover, calling `hack-local-variables' 
does not prevent its subsequent call after Org mode is loaded, which sometimes 
causes double unsafe variable prompts.
See

Would it be possible in Emacs to implement a function or possibly major-mode 
option that will make Emacs load local variables before loading major mode, not 
after?

Best,
Ihor
