Hmm. Not completely useless - it will still effectively compare between
Org version in org-version.el and org-assert-version.el. But indeed less

Does it solve the problem with "make install" on Debian?

I may be missing your point, but `load-prefer-newer' maybe?

This is because `org-assert-version' was not defined in Emacs during
compile time. During compilation, Emacs produces byte code calling a
function. AFAIU, the byte code is equivalent to
(funcall #'org-assert-version), which fails with error (try it with M-:).

straight.el has a special arrangement for compiling Org. See
Basically, it spawns a child Emacs process and thus does not struggle
with mixed compilation state. (I am not 100% sure about the "make
install" issue you encountered).

The main issue with straight.el is its design - straight.el has no
equivalent of `package-selected-packages' and instead loads the packages
as they appear in the init.el. It is a problem when some statement has
(require 'org) early in the config, before straight sets up the newer
Org version.
