As you quoted
"for compatibility with existing implementations."
To prevent code breakage in VFX Forth systems both hosted and
embedded. MPE has been using the nortation
: foo { a b | c d e[ 5 cells ] f[ 7 cells ] -- }
for local arrays for 15 years or so. I'm not silly enough to
put forward a proposal that will break our own code. See the
local buffers proposal.
The point of this proposal is that it introduces uninitialised
local values as well as local arguments.

See the reference implementation(s). Yes, there's carnal knowledge
involved, but if you've already implemented (LOCAL), implementing
BUILDLV is trivial. AS I've already said we've used it for 15 years,
and variants with a similar notation exist in Win32Forth and gForth.
