I like the idea, but:
AFAIK the main issue with pseudovectors is that their allocation is
slower and suffers more from fragmentation (because we don't use
a size-segregated allocation algorithm (like Linux's SLAB, for example)
Are you sure the new code is faster overall?
There is also a potential issue in terms of the resulting heap size of
markers (which may bump up from 6 words to 8 words, IIRC, unless your
patch does something to keep it down to 6), tho this is probably of no
