Just an FYI , I didn't write this dts or work on it's original development so I
can't name names.

I'm not sure what your talking about above .. Are you suggesting the changes in
my DTS will change quickly ? They have been the same for years , we don't plan
to change them. This DTS is not a prototype it's a released Cisco product.

If I did delete this "PL configuration" where would you expect it to re-appear ?
Typically things which aren't upstreamable are transformed into something else,
it's rare that something is just removed and has no transformation.
