bq. That's why the pre-existence (and reasonable adequacy so far) of DESCRIBE
is very relevant to me: since we've not removing DESCRIBE in cqlsh, pushing it
server side is really the only option that does not create 2 ways to "describe
the schema"
This makes sense to me and I think this is a big reason to not do a virtual
table, unless we are going to remove DESCRIBE from cqlsh and start telling
users that they get back the schema with {{select * from ...}}

> Currently the drivers recreate the CQL for the tables by putting together the
> system table values. This is very difficult to keep up to date and buggy
> enough that its only even supported in Java and Python drivers. Cassandra
> already has some limited output available for snapshots that we could provide
> in a virtual table or new query that the drivers can fetch. This can greatly
> reduce the complexity of drivers while also reducing bugs like
> CASSANDRA-14822 as the underlying schema and properties change.
