Yes, this may be a problem for ordinary Emacs Lisp file.  But I'm
talking about autoloads.  It is a special file that defines autoloaded
functions.  Calling autoloaded functions will automatically load the
file containing the actual definition.  Autoloads files should not
depend on there names, and if they does its probably a bug.  All
autoloads files are needed to load at runtime, so concatenating all of
them should probably be a good idea.  Emacs builtin package manager
"package.el" and third party purely-functional package manager
"straight.el" both support merging the autoloads into one file.

But load many autoloads files is not a big problem, the main problem is
the messages "Loading...", "Loading...", "Loading..."...
