Hi all,
I often find myself in this situation – one rehearsal mark (E) is situated high and causes the vertical spacing to go awry:
I can manually move it down:
But this does not do anything to the staff spacing. I don’t want to turn off collision avoidance completely, but it would be neat to switch it off for rehearsal marks. Am I right that this is not possible?
Is there any other smart way to deal with this other than manually dragging staves in Engrave mode, staff spacing?

Only thing I can think of is to delete the rehearsal mark in such a spot and add it with system text using the Rehearsal Mark paragraph style with a border, and then adusting the index for the next (actual) rehearsal mark to maintain the sequence. The downside is that it can be a pain to get the padding and border exactly right if you want it to exactly match the real rehearsal marks, but at least you can turn collision avoidance off.
No, at the moment there’s no way to exclude rehearsal marks from being considered for vertical spacing.
If you manually nudge the note spacing of the first note of the bar to the right, I think it will solve your problem.
Or move the RM backward in Write mode, that way it will get out of the way… You can then reposition it in engrave mode, but with the spacing intact.
Just to be clear, I consider this a workaround and do heartily support the choice for collision avoidance with rehearsal marks! 
+1. This would be a huge time saver for me. This comes up most often when I need to have a segno and rehearsal mark on the same barline, but in any event, I’d most often want less space left than Dorico seems to default to for rehearsal marks.
Another option for request to the programmers might be a “best placement” setting for items above the staff. An algorithm for best placement of items that might cause such large gaps, with user control over gap threshold. In other words, doing those things we would have to do by hand in Engrave Mode to fix the look.
I expect that would require a lot of code, however. Though, who knows? The way Dorico is designed might allow for this easily.
This is a huge time-waster for me, currently.
If I have a tempo marking and a rehearsal mark, Dorico tosses the mark forty feet above the staff and then refuses to respace the staves of the page even if I fix the “collision,” or even when I create a frame break (which usually otherwise respaces the staves on the page).
Also happens if there are notes in leger lines above the staff on both sides of the barline.
Or mayhaps an errant slur across the barline.
I love the collision avoidance. Except when I don’t. But I’m not willing to throw the baby out with the bathwater and turn it off.
One only turns it off where there is a conflict; it’s not an all-or-nothing proposition.
