It's a hack because it's a common case which every affected user ends up 
fixing through editing their init file.

Or the OS used, with its different performance characteristics. And the 
performance of the W32 Emacs port as well. Anyway, this is beside the 
point, since we'll always want more improvements to performance, of 
course, to be able to handle larger projects on slower systems.

If you want more food for thought, look up my previous messages in this 
thread regarding "subprojects". And others' too.

In this thread people are asking for a change in Eglot's behavior, and 
not in project-related commands. For example, to keep 
'project-find-file' listing all files in the parent project, not just in 
the current subproject.
