Does Openreach support BitSwap, or SRA?

All Openreach VDSL2 products will use bit swapping.

Yes.

OpenReach VDSL2 uses bitswap.
OpenReach G.Fast uses bitswap and SRA.

OpenReach were trialling SRA on VDSL2 but nothing appears to have come from the trials.

SRA seems less useful than I originally thought it was, if it can only reduce the speed not increase it.

Its primary purpose isnt to increase speed, for me the benefit was to deal with significant amounts of variable noise on a line without interruption to service.  Now you get an effective speed increase as SRA will auto recover speed if snrm goes back up after a reduction, whilst if you sync at a lower speed without SRA, if SNR increases you wont recover speed without another resync.
