This is an interesting question I have no definitive answer for, just wild guesses:

- Because the shitstorm from the devs would be immense?

True

- Killing SDA might have been a test case for killing SEU in the future?

Possible but I'm not convinced,

=> That would leave the platform without any local editor, not just for code. A serious lack, IMHO!
- Because IBM at one point has already rewritten SEU to a supportable code base?

Nope. But SEU has had a number of upgrades over the years and certainly a lot more in the way fo partial rewrites than SDA. SDA had to change to accept RPG IV, C, ILE COBOL, etc, SDA just went on eating DDS whoich didn't change that much.

Ahaha, that would probably leave those Big Brains with big headaches. :-) I've been told that in earlier times, OS/400 wasn't built (compiled) in OS/400 but in AIX, and then transferred to the platform somehow. Not sure if and to which extent this has changed since those days.

When I was first there everything was compiled on mainframes and the resulting code stream downloaded. I _think_ more in the way of OS builds started being done on AIX around the time the hardware converged.
