Hello,

By default, base::flat_set and base::flat_map cannot be used inside blink.
However, there are about a dozen carve-outs
<https://source.chromium.org/search?q=base::flat_%20f:audit_non_blink_usage.py&sq=&ss=chromium%2Fchromium%2Fsrc>,
and I'm wondering how people would feel about relaxing the restriction more
generally.

My guess is that there are two primary reasons for the restriction:

- No support for base:: containers of garbage-collected types
- Mixing redundant/overlapping WTF and base containers could create a big
mess

Are the other reasons I'm not thinking of?

How hard would it be to modify the blink GC clang plugin to forbid base::
containers of garbage-collecte types?

My motivation here is that there are cases (including one I'm struggling
with right now) where structured data is stored in a base:: container in
cc/, passed to blink/, and then passed back to cc/. In some cases blink
does not use or modify the container; it's just a conduit. In those cases,
we either need to do a pointless round-trip base->WTF->base conversion; or
we need to add entries to audit_non_blink_usage.py which creates a blind
spot for enforcement.

Thoughts?
