This looks like a solution in search of a problem.
"ignore" the same as not having a TryExec key at all, "hide" is what we have,
and "delete", well, I certainly wouldn't want to enable a feature that deletes
my carefully crafted .desktop file because of a typo in TryExec. (and system
desktop files are typically not deletable, so this is indeed really only about
user desktop files)
