CMF may have a bug in its check whether something changed on disk (only
performed in development mode).
This is long known for Windows versions.
Recently, someone seems to have spilled this bug into non-Windows versions,

We use deeply nested folders in skins (3 levels with hundreds of leaves)
and do not see any problem
(our CMF version has a fix for the "checking inefficiency").

If it should turn out that I am right, then please file a bug
report. The "checking inefficiency" can definitely be fixed...
I had long discussions about it with Chris Withers, months ago.
I fear, he did not fix it -- despite the long discussions...
