I imagine that they would support a fork provided that:
-The value of it was high enough for their users to demand it
-It had a functioning codebase
-It was secure for them to implement support.
However, since "Bitcoin Gold" was an extremely shady group who listed a scam on their website that stole millions of dollars, failed to protect their official client from malware and basically rode off the back of BCH anyway, I find it hard to believe that there's any more relevant forks to come.
Were did you get your info that btg is such a scam, would be interested to hear more.
