The main problem is that inspecting Ion frames wouldn’t work. So we have a
plan to fix that:
Bug 923724 - Inspect Ion stack frames in the Debugger, very carefully
https://bugzilla.mozilla.org/show_bug.cgi?id=923724
Just for information, during the last JS work week I mentioned that there
was no safe way to inspect the Ion stack under any Call. This used to be
true, until recently.
Now, we have the OSI Point checker which is ran by fuzzers. This means that
what could be unsafe in theory is safe in practice based on our current use
cases (and assertions). This also mean that we can use the Safepoint to
read the content of any Ion frame.
