For the same reasons you don't store existing comments in a user-defined
table:
1. It's convenient to have a standard (across providers) place for them.
2. It's meta-data, not data.
3. It gets dumped along with my table.

If it's just a case of "looks like a waste of time" then I might well waste my
time and do it. On the other hand, if it's a case of "unnecessary
complication - don't want it in the code" then I'll not bother.
