This is probably fine as the reason is observable.  It is true that some TLS alerts are hidden, but that is generally because that leaks private information.  But here the information is public, or at least shared by client and server.

Is the concern that this is potentially sent in an Initial frame?  Because that shouldn't be necessary, or even possible.
