Are quirks officially counted as disadvantages?

Page 11, right under Disadvantage limit.

Disadvantage Limit
A disadvantage is anything with a
negative cost, including low attributes,
reduced social status, and all the spe-
cific disabilities listed in Chapter 3.

Note that quirks are in chapter 3, which is labeled disadvantages, and have a negative cost.

GCA has the weight of being the official SJG endorsed character building program. GCS does not, so using it as an argument one way or another on the rules is about as "authoritative" as using the forums here.
