What is the use case for temporary tables on a hot standby server?

Perhaps this is a noobie question, but it seems to me that a hot standby
server's use by* applications* or *users* should be limited to transactions
that don't alter the database in any form.

However, I can see where temporary tables might be needed at the system
level (if not already available) in order to prepare more efficient plans
for some complex read-only queries.
