[BUGFIX lts] Revert container deprecation

We agreed that it was important to fix the error cases in #18717, but while the work may be unnecessary, there isn't necessarily any "correctness" issues with looking up things during destruction. Using a deprecation to warn about potentially "unnecessary" work is a bit heavy-handed, and at minimum requires some more continued discussions, so reverting that part of the PR for now (while keeping the errors in tact). (cherry picked from commit b853324)
