Hi Mikel,

I did not say that I am against the validation rule itself. I agree that
the rule is a great step forward. However, the turn-validation-off tag
is not necessary because most buildings are edited only one time:

ways with building=* except building=no:      341403310
  thereof version == 1:                       277493561 (81.3 %)
relations with building=* except building=no:    630284
  thereof version == 1:                          406731 (64.5 %)

Limited to objects edited after 2017-01-01T00:00:00Z:

ways with building=* except building=no:      151163160
  thereof version == 1:                       125435755 (83.0 %)
relations with building=* except building=no:    349731
  thereof version == 1:                          184564 (52.8 %)

Best regards
