Review Comment:
@rdblue @aokolnychyi @namrathamyske As discussed in the community sync,
we'll remove the SQL write option from this PR and take that separately since
for row level operations there's more fundamental changes that need to happen.
I have those changes ready along with updated merge tests, so I'll publish that
so folks can take a look

Review Comment:
@rdblue @aokolnychyi @namrathamyske This will prevent any row level
operations (temporarily until the SQL write config PR gets in) on non-main
branches.
Not entirely sure of a good way to test this because the only way to hit row
level writes is via SQL and we're removing the SQL config anyways. This is more
of a defensive measure in case there's a case for row level writes not via SQL
that we're missing.
