1.4.4 and later eliminate redundant 0 scaling factors, but this one
isn't actually redundant:

If it was on the right-hand side of AND_NOT it would be eliminated
(because the right-hand side doesn't contribute any weight anyway).
FWIW, I also couldn't reproduce this (I tried with quest and 1.4.7):
$ quest -psubject:S -fdefault,boolean_any_case 'subject:"and"'
Parsed Query: Query(Sand@1)
Cheers,
