And the recommended way is trivial (even though anaconda should really set
up the alias at install time)

What won't be trivial *at* *all* is if you encourage app authors to invent
their own one-of-a-kind not-really-tested communication stack. God knows
they are already leaning towards wheel reinventing without any such system
blessing.

Set up your own replacement. Make it good, secure and easy to operate.
Have it widely adopted. And then you can talk about removing the default
MTA. If it's good enough you have nothing to fear about MTA competition.
If you do need MTA removal to get your stuff adopted, well, that only
tells me your stuff is crap.
