The meaning of "p1 & p2" would be "yields a pattern that matches both
p1 and p2" versus the meaning of "p1 && p2" currently being "yields a
pattern that matches a p1 followed by a p2" ?

I'd generally say that deprecating (emit a warning message pointing to
each usage) for a time period is a more cautious approach.
