Yes, we need them because we need a new contract.

But those are not the descriptors you are looking for.

The translation strategy will use classic L-descriptors
for the old contract and new descriptors for the new

If a class C is an indirect class, then only L-descriptors
"LC;" will be used.

If a class V is an inline class, then either "LV;" or "L*V;"
is in play (where L* is a new descriptor kind Q, G, etc.).

The tricky bit is that V natively translates to "L*V;" and
the projection V? translates to old-contract "LV;".

Thus, any given "LV;" in a classfile might either be some
classic C, or some V? for an inline V.

So there's a side bit required.
