Presumably, this refers to

As has been said before, you will need either (a) An endorsement from BA or (b) To read and follow the guidelines on
https://springrts.com/wiki/Licenses_Forking_Mutators. It looks as though almost no effort has been made in this direction - the game linked above does not do so in multiple, obvious, ways.
For example, it imitates BAs version numbering, 9.46.x. It includes loadscreens featuring games of BA (i.e. all of them). An icon that says "BA" is displayed when in windowed mode. It is currently hosted on servers that are associated with BAs infra - and up until recently actually hosted BA.
The ingame changelog lists a "BA feature merge release", without offering any details. Please note from the guidelines: "mutators should be used by projects that incorporate changes found in new releases of their parent game ... Forks should be used by projects that tend not to incorporate innovations found in new releases of their parent game."
The changelog could also be interpreted as intentionally insulting to BAs devs ("Changed MOD name to avoid tears and excuses from nerds wanting to ban it"), which should be avoided.
In short, whilst having a name that does not include "Balanced Annihilation" is a step in the right direction, it looks as though nothing else has been done. I can't see evidence of any serious attempt to follow
https://springrts.com/wiki/Licenses_Forking_Mutators. As a result, the answer to this request remains: no. Please address the issues above, and follow the rest of the guidelines.
In view of the multiple previous warnings, which have continued to be ignored -- without BAs endorsement, we will need to see that the forking/mutator guidelines are being followed in good faith for a significant period of time before the game is given access to a forked copy of BAs data.
