Provisionally removes previously added literal profile from SSSOM (#383)

Intermediate PR to make it easier to review the new solution for

Note to reviewers: Whoever approves this, intrinsically approves also
#384 (modulo details). The point to merging this first is to make
reviewing #384 much easier.
