Change:
This is for injection of out-of-band shared entropy.
Note that an alternative to this is to make PSK a proposal containing a PSK identifier.
I forgot to push my last commit when merging there should be a non-empty context for within the just after the PSK. Fix this when doing step 2 to keep close to the TLS importer...
Think this is obsolete given recent revisions to Derive-Secret

Discussion:
6.7. <ins> Groups which already have an out-of-band mechanism to generate shared group secrets can inject those in the MLS key schedule to seed the MLS group secrets computations by this external entropy. At any epoch, including the initial state, an application can decide to synchronize the injection of a PSK in the MLS key schedule. This mechanism can be used to improve security in the cases where having a full run of updates accross members is too expensive or in the case where the external group key establishment mechanism provides stronger security against classical or quantum adversaries. The security level associated to the PSK injected in the key schedule SHOULD match at least the security level of the ciphersuite in use in the group. Note that, as a PSK may have a different lifetime than an update, it does not necessarily provide the same FS or PCS guarantees than a Commit message. [[OPEN ISSUE: We have to decide if we want an external coordination via the application of a Handshake proposal.]] 6.8. </ins> As described in message-framing, MLS encrypts three different types of information:
