I thought the whole point of using PEX was to eliminate as many connections
as possible, particularly ones inside of walls where the mechanical seals
could leak unnoticed for some time. This would rule out Tees and Ells and
promote home runs from a manifold and using curved tubes to make 90 degrees.

I certainly though that was supposed to be one of the big advantages,
coupled with the flexibility that allows you to fish it continuously.
Exact same idea as the flexible stainless gas line that's beginning to
replace the old black pipe with all it's potential leak points.
