Stack snippets are available on this meta.stackexchange.com site, but as mentioned in the initial meta post about them there was no discussion as to whether they should be here or not.
I would suggest they be disabled / removed from this site.
We get many off-topic programming / code questions here, and the fact that the snippets buttons render within the questions gives those questions a sense of legitimacy, potentially indicating to the poster that their question is actually valid here, when that is likely not the case.
I'm sure there are some valid use-cases for having them around - sandbox testing for instance - but that could be mitigated by referring people to the a sandbox post on MSO instead.
Do we need stack snippets on a site dedicated to questions about Stack Exchange? We would still be able to discuss them, but I don't think there's a need to actually implement them here.
