--- Comment #8 from Eric Pouech  ---
finally a solution has been upstreamed in
50c45eb0e15121ccd2fccd432a7b40b3cf18908c

note that it's a different solution from #2

(in a nutshell, #2 creates -incrementally- a full table of all labels in
command file, while merged solution caches the result of previous label
searches)

so #2 can provide better performance (when the file isn't modified), while
committed solution has a fixed size for cache storage, and is simpler to
implement an maintain
