That's *clearly* backwards.  Ignoring our little argument, I think there
is no denying that temp views as such are useful --- for example,
consider a temp view created on permanent tables to define a
session-local shorthand for a complex query.

If you want a restriction, make it* Invent temporary views* Restrict permanent views from referring to temporary
tables
I agree with the first goal and disagree with the second --- but I can
see your point of view on the second.  OTOH I can't see any reason to
hardwire tempness-of-views to tempness-of-referenced-tables, because
that disallows the obviously useful case of temp view on permanent
table.

It was right the first time.
