Do you think this check is better here, in the sink definition, or in the place where the query uses the sink (as it is for rust/access-after-lifetime-ended)? Should we be consistent between the two?

I think it makes sense to have for the sink, if it's intended to represent pointer dereferences. We should remove the check in rust/access-after-lifetime-ended. I've done that now.

// We are only interested in dereferences of raw pointers, as other uses
// of `*` are safe.

I'm interested to see if this PtrType restriction effects real world [edge case] results (DCA and/or MRVA).

Sources needs to satisfy this in the end anyway, so we might check for that here to prune some sources earlier in the process.

This check is weird, but note that the check before the changes had the same effect of excluding all nodes without an expression. So this is only preserving what was already there.

Since my present goal is to improve performance I don't really have appetite for introducing additional sinks, hence I left this condition in place.

As the todo says I think we should try to remove this in the future and see what it does for performance and results.
