We certainly must avoid the build break.
My concern is that CONFIG_DM may introduce a run-time break. For example if you don't have pre-relocation malloc() available the board may not boot. Driver model is a fundamental core feature, and we are working to move everything over to it, but I'm not quite comfortable with forcing it on when someone changes a feature. It feel it would be better to not offer it.
I'm interested to hear other viewpoints though.
Perhaps soon we can enable CONFIG_DM globally but we are not there yet.
I appreciate the caution.
For now, vexpress works with qemu which means I can get back to playing with verified boot. I haven't checked to see if it's possible to make RSA not always require DM - I defer to those who know the code better than I do.
