Is there any plan to migrate to wolfssl or mbedtls?

OpenSSL may be a little too big for embedded devices.

Not really, we do have gnutls and few other crypto library's support (libnettle, libsodium). Do you think it would be easy to include those as well? Would you like to help building support for them?

I'd like to see this but cannot really contribute much more than this comment.

I've recently stopped using Stubby on an OpenWRT router because of the getdns OpenSSL dependency. OpenSSL was just too big for the resources I have.

I know the current OpenWRT wolfssl package (that I now use) is configured with --enable-opensslextra. And checking wolfssl documentation it seems they supply a compatibility header:

When time permits I'll have a look
