> Is there a plan for purging old data from this one?

Just to make expectations explicit:
Since in a different part of this thread you are asking more for
expected growth bounds, I assume that the table can stay at that size
until discussion with Language about the way forward produced concrete
next steps, and you do not expect us to prune data right away.

I noted that too when looking at the issue last week, but decided
against calling it out, since it's just a single small table.
I expect we see these artifacts from time to time. Do they get in the
way somehow, or is it ok to just keep them around?
