As stated in the RKV documentation, it is absolutely required to use the "safe-mode" backend for any product that is intended to ride the trains to beta/release: https://github.com/mozilla/rkv#%EF%B8%8F-warning-%EF%B8%8F To my knowledge, Glean has been using the LMDB backend for RKV successfully in the past, because the platforms it was shipping on were coincidentally not affected by the crash. In order to ship Glean on desktop however, an update to a recent version of RKV was needed. To my knowledge, it was done in https://github.com/mozilla/glean/pull/1322. We should either uplift that to beta, or skip the current train.
