Thomas Habets points out on the trousers-users list that TrouSerS, the open source TPM stack, is getting kicked out of Debian, due to it’s lack of OpenSSL 1.1 support. I hope someone at TrouSerS is working on this. Tomas has a similar tool, Simple-TPM-PK11, and has made similar changes in his tool, that TrouSerS will need to do, and describes this in his post to trousers-users.
