But if _every_ entry has a visible PROPERTIES drawer (because a
creation and last-modification
dates of the entry are stored there), then entries for which custom
export options were set no longer stand out.
Just as, if you BOLD every word in a document, BOLD no longer acts as
a highlight.

So, I agree that unique customizations should lead to a visible indicator.
But for properties that aren't really customizations ( creation date,
modification date, unique ID ),
a visible indicator only clutters things without acting as a useful highlight.
So, what about making a UNIVERSAL_PROPERTIES drawer that is normally
completely hidden,
unless you explicitly reveal it?
