From what I can see these signs are basically identical in meaning, and there exists no tagging for the new version of the sign.
Correct. The meaning of these signs is identical. The new variant is the European standardized one (EN 16494).
I think it was a genius idea to add the ":shape" subtag (*cough* *g*), and this could be easily used here:
railway:signal:train_protection=DE-ESO:blockkennzeichen railway:signal:train_protection:shape=circle
or
railway:signal:train_protection:shape=arrow
For the time being we must treat a missing :shape for the German signal as "circle".
Afterwards we can start adding a rendering for this, which should be easy as it's just a copy and color change of the "ETCS stop marker" image.
It differs a little bit - the arrow has no border, but the board itself has one: https://kuemmling.eu/orm/ETCS_location_marker_left_side.svg
Part 2:
Since this signal comes from the ETCS world it is likely in use outside of Germany already, the German wiki page e.g. refers to Swiss "ETCS- Standortsignal". The question is: how is the tagging of this type of signal in other countries? Do they also use different shapes or does only the arrow form exist there? Would be nice to know as that could be added to the rendering rules at the same time.
I'm not sure whether there exist any standardized ETCS location markers outside Germany yet.
Location markers in another non standardized variant (white triangle on blue board) exist on some high speed lines in Italy (e.g. Bologna - Firenze).
