Such new Delphi features are only enabled by default in FPC modes if
we consider them to not run counter to the spirit of Pascal. That's
obviously subjective, but so is Embarcadero's decision to introduce
them. There will never be convergence, because Embarcadero is not
interested in that.
Sorry, I didn't understand your point.
Out of Embarcadero subject, if 100% convergence is not possible why do
divergence?
Are you agreed that more FPC is compatible with Delphi "by default",
more users can use it without troubles and learning additional docs?

You can use {$modeswitch advancedrecords} to enable them in any
non-Delphi syntax mode
(http://www.freepascal.org/docs-html/prog/progsu106.html ). Virtually
all new language features we add these days can be selectively enabled
and disabled via mode switches.
This is a good example of complicating the life.
"One option by feature" to activate every new language feature lead to
growth of end-user documentation and using $MODE DELPHI when it is not
required at all.
In the perfect world $MODE DELPHI should be required only to compile
same unit in both Delphi and FPC.
Why move away this perfect world?
Making the simple complicated is commonplace; making the complicated
simple is hard, that's creativity.
