I've thought a bit about the "set step ..." suggestion, and I
remembered Michael's "set/show enable-software-singlestep"
command, that could also fit there.  So, I guess we could have:

For displaced stepping:

 set step over-breakpoint auto (on if there's gdbarch + nonstop support)
 set step over-breakpoint displaced/ool/out-of-line
 set step over-breakpoint step-and-hold

 (or shorter versions)
 set step breakpoint out-of-line
 set step over-breakpoint ool
 set step breakpoint ool

For soft/hard single-stepping:

 set step single-step auto
 set step single-step hard
 set step single-step soft

 Or shorter versions:
 set step single hard
 set step single soft 

...
