Are you not worried about being able to tune these things on your non ebb frame?
I don't think its an issue really, set it all up once and then it's done. If you have to move the ebb to take up drivetrain wear I doubt it'd be by enough to notice the difference in bb height and setback.
I'm about to go the ebb route - any view on which BB to use? I've been recommended the Philcentric for Shimano (as BB30 had potentially too little adjustment and Beer doesn't actually support that many cranksets).
Used Phil's on my Singular Swift for one year of commuting, with practically no maintenance. It was heavy but basically set and forget and good quality.
I personally prefer compared to my experience with sliding dropouts, which I had to re-tighten quite often
