If you want to release a community version of LE for that device via these forums you are welcome. I would not accept it as a formal addition to our roster of build projects as that is not necessary. The 8723bs driver appears to be in the staging area of the 4.12 kernel which is a couple of months away; once available the kernel config and firmware required can be added to the Generic project. If there are other changes required for other areas of hardware support - please submit the changes for review. Having someone actively interested in these devices would be nice as we don't have many (if any) of them among staff.
NB: Our master branch (LE 9.0/Leia) will move to 4.11 kernel in the next ~week when it's released. Once we bump someone normally creates a PR to start accumulating the changes required for the next major version bump (i.e. to 4.12). Please comment and direct people on changes needed.
to be clear, all development should be done against the master branch. We can then assess the changes and make decisions on what items can be backported into the 8.0 branch which has tight change control as it is an active release branch.
