I'll see your two examples and raise you one, Skipp. (GRIN! Or maybe 2...)
Example 3:
At least two controllers now support CTCSS detection and/or generation
directly in the controller.
The S-Com 7330 (currently in beta test) offers CTCSS encode, but not
decode:

The PSE-508 series from Pion and Simon Electronics handles both encode
and decode, but is built to be installed into a specific repeater, the
GE MASTR II. (In fact, their latest software rev offers 4 CTCSS tone
"community tone panel"-like functionality.)

Wasn't there also a Pacific Research controller that did one or both of
these at one point? They've always been too expensive for me, but I
thought one of their boxes did it... maybe... ?
I think putting the encoder/decoder up in the controller is "the wave of
the future"... if done right, it should make things a lot simpler in the
long-run... no fussing with CTCSS boards in any fashion, just bring
discriminator audio to the controller and find a place to send audio
back that isn't high-pass filtered... done deal...
The controller folks making the CTCSS circuits have to go out and get an
"edumacation" on Reverse-Burst/STE and all that fun and games though, if
they want to fully emulate the original manufacturer's boards... I know
the 7330 is going to have the option to do "either type" of phase shift
on their encoder, for example. Not sure if the P&S does RB/STE at all.
Example 4:
Go digital, leave the silly CTCSS behind. The 70's are calling and they
want their repeater back!
Heh heh. :-) :-) :-) !!!
