You mean page zero, which is currently always pag_header. I see no
reason
to change this, so far. Header page uses to describe properties of database
and could be extended to describe pagespace when necessary.
I have no objections. I suppose it will be used for nbackup implementation at
least.
BTW, how are you going to prevent a tablespace file from being declared in
two or more databases simultaneously?
