I often ask myself the same thing ;)

Paul has a THAT-based envelope follower in the works.  I have high hopes
for it -- up until this point, no other envelope follower has used that
level of technology.

The Oakley Multimix has a very nice UI.  I have one with a 1U Stooge panel.
It can be used as an AC/DC mixer, inverter, scaler, DC source etc.  For
myself, I like it much better than Paul's proposed micro mixer interface.
It's very flexible -- similar to a Serge signal processor.  However, the
Oakley does have room for improvement on the inside.  It could use more
bypass caps and provisions for shielded cable.  I decided to unpopulate the
"capacitive load drivers" on mine, and used the OP275 which is already
designed drive shielded cable.  It's DC specs are decent (offset of a few
hundred uV), but not quite good enough to control VCO's.  You could use
LT1013's instead (60uV voltage offset), but they're bad for audio.

Otoh, according to the MOTM website, the 830 has excellent DC and audio
specs, with a DC offset <1uV (?!?) suitable to control VCO's. (Although it
worries me that its author says TL072 designs are "OK" for audio ;) It also
has an adjustable DC bias source.  If it used insert cables for the reverse
attenuators (afaik, only the 850 has a TRS jack) it would be far better
than both the Serge and the Oakley in every situation, but it doesn't.  So
there is a trade-off between quality and flexibility.

Perhaps you should get on sdiy -- it's back up.
