I can't go to Lisbon, but my personal pain points are all this:
https://openwrt.org/meta/infobox/broadcom_wifi
and I think I'm not alone, but I can't speak for OpenWrt.

The lack of support in b43 for modern phys such as AC, i.e. the gap
between b43 and brcmfmac, is extremely annoying and turning perfectly
fine aftermarket devices into paperweights because there isn't even
a way to make Broadcoms old proprietary blob work with contemporary
kernels.

If Broadcom could be convinced to either add support for the late b43
variants or at least release documentation for the aftermarket that
would be great.

I suppose they might be coming to the conference so give them my best
regards with a "please fix" tag attached.

Yours,
