ETL's solution to the same problem was the auxiliary anode tube (GSA10G and GCA10G) which effectively combines the two operating modes - counts like a dekatron, but drives the nixie via a separate set of electrodes. Both polyatrons and aux anode dekatrons are neat solutions, but fundamentally by the time they appeared the whole field was well on the way to TTL counters. Probably polyatrons got more use in the Soviet Union as tube technology clung on longer there.
