Then we have the page-crossing issue. Is it better to force the
compiler/assembler to align such instructions so that they never cross
page boundaries?

Power 10 chose to do so; actually, larger instructions cannot
cross a (likely) Cache line size there.  According to the Power
ISA Version 3.1, section 1.6:

"Prefixed instructions do not cross 64-byte instruction address
boundaries. When a prefixed instruction crosses a 64-byte boundary,
the system alignment error handler is invoked."
