Yes, AFAIK arc commands were dropped somewhere between 2004 [1] and
2005 [2], although I'm not familiar with most recent (WG-internal?)
working drafts of the specification regarding this particular matter.

Although related but slightly off-topic, I'd like to take this
opportunity to suggest adding a reverse implementation notes for arc
commands; that is, as SVG 1.1 curve commands [3] had arc
implementation notes [4], IMHO it would be interesting to help
developers/authors in the migration to SVG 1.2 process by clearly
explaining how to perform arc to curve commands conversion (maybe
attached to path section [5]) so that content migration could smoothly
take place - a "downgrade", in this particular case. Does this make
sense? Should a separate thread be created to discuss this particular

Best regards,
