I think it is good to at least make it clear when a LEP is
abandoned/out-of-date. (This could be deleting it, renaming it to an
'old' state, marking 'this is now obsolete' at the top.)

The rest is bookkeeping that has some value, but also some cost. If
people don't do it consistently, then you can't trust that any given LEP
is up to date. Are people really going to be referring to an old LEP to
figure out what to do next? Or are they just going to be submitting a
new one.

I would tend to say, allow for a big hammer of "this is now obsolete",
but if people want to maintain a lep that is partially complete, then
they are certainly allowed to do so.
