Delphi's decisions are irrelevant. (and they regroup across directories
every other version too)

There is no reason to compile these reasonably large units 3 times. The only
reason to keep them in the base RTL is because units there would need it (like a
unicode classes version)

Then consider spinning that out to a lower level unit. It is not a reason to
stuff everything and the kitchen sink in the RTL.

In forks you are free to modify and move whatever you want. Usually in cases
like this the developer doesn't want to use the more conservative version
packaged with FPC, but one with a quick feedback with own changes.

And isolated in a package they are more easily disabled (edit one fpmake)
then in the RTL (edit all targets makefiles)
