Are microfilters still required without telephony?

I recently renewed my FTTC contract and lost telephony. All working well but is a microfilter still necessary? The router cable plug won't fit directly into the BT point obviously, but there may be a suitable cable for that. My thinking is that I could simplify the connection, reducing clutter and possible failure points, and improving speed at the same time.

Technically , no. If you look at the schematic for a typical DSL filter, the DSL port is a direct connection to the line, all the filtering is on the phone side. Having said that, a DSL filter is probably the simplest way to convert the RJ11 to BT plug.

Or fit a NTE5C Mk4 faceplate with separate phone and VDSL sockets.  I believe if you already have an old single socket 5C the Mk4 filtered front plate is a straight swap.

Presumably, as the 'phone socket will become redundant, faceplated with only the VDSL socket will become available.

As most people, if they have the option, will be moving to FTTP, you won't need a phone socket - or the VDSL one.

I rather suspect there will be lots of customers who won't have the FTTP option - rural, awkward for other reasons, or awkward landlord (block of flats, campsites, other such) who won't allow access across their land/building to lay the fibre.

10 minutes walk from Deansgate at the centre of Manchester my building doesn't have FTTP. It will take a while for the whole country to get it.

I was hoping to get rid of that microswitch hanging from the BT point, but I suppose I will have to live with it for now.

Re: Are microfilters still required without telephony?

As noted in another thread I just hard-wired an RJ11 cable to the connectors on the backplate and clipped a simple shallow BT plate to the front. Really it now just needs a blanking plate! Are they available for the latest NTEs?

The plug-in filter, if used, only functions as an adapter between the BT socket and RJ11 cable to the router.

My understanding is that the Openreach Mk4 faceplate incorporates a RF filter which is there to increase line stability by reducing the effects of REIN (Repetitive Electrical Impulse Noise).
