Smalyshev added a comment. I'm not sure why it is the only way. Certainly using Somevalue or string or any other placeholder value are ways too. They can be worse ways if you see arguments against them but why they are not ways at all? Why these ways can not be considered? Also, we're not talking only about year 0 - there are many non-Gregorian dates there.
Judging by this: http://milenio.dcc.uchile.cl/sparql?default-graph-uri=&query=PREFIX+%3A+%3Chttp%3A%2F%2Fwww.wikidata.org%2Fentity%2F%3E+SELECT+count%28%3Ftime%29+WHERE+%7B+%0D%0A++%3Fx+%3Chttp%3A%2F%2Fwww.wikidata.org%2Fontology%23time%3E+%3Ftime+.+%0D%0A++FILTER+regex%28str%28%3Ftime%29%2C+%22%5E0000%22%29+.%0D%0A%7D+&format=text%2Fhtml&timeout=0&debug=on We have 51 entries with year 0 (if the data there is full and up-to-date) and 3541 negative dates. Not sure how to count invalid dates but there is a date like "1966-02-31"^^http://www.w3.org/2001/XMLSchema#date in the DB there which doesn't look like a valid one - looks like Virtuoso is more lenient in allowing invalid data than BlazeGraph. We also have 12806 entries marked as Julian.
