A lot of StopPoints in NaPTAN – 5000+ in London by my count – have the Indicator “Stop” rather than e.g. “Stop F”. This seems to be a recent regression and they included the letters before ~27 August, even though many of the stops in question have a long-ago ModificationDateTime
E.g. Stop P:
<StopPoint CreationDateTime="1970-01-01T00:00:00" ModificationDateTime="2016-10-06T06:35:57" Modification="new" RevisionNumber="13" Status="active">

I’m aware that fortunately I can still get the platformName from the unified API, and I think the journey planner timetables TxC data includes the full indicator still. Also appreciate that this may be a low priority at the moment.
