Re: [whatwg/dom] Proposal: moveOrInsertBefore() (Issue #1406)

We should consider the performance constraints of JS code like that. It's been a while for me looking at stuff like this but `try`/`catch` in a hot path could impact perf. If on the implementation side we're just checking a flag, then it might be enough to provide a reasonable justification to add to the platform - but I think emperical evidence is necessary.
