 `[PSA_WANT|MBEDTLS_PSA_ACCEL]_ALG_FFDH` allow builds accelerating FFDH and
 removing builtin support (i.e. `MBEDTLS_DHM_C`).
 
+Note that the PSA API only supports FFDH with RFC 7919 groups, whereas the
+Mbed TLS legacy API supports custom groups. As a consequence, the TLS layer
+of Mbed TLS only supports DHE cipher suites if built-in FFDH
+(`MBEDTLS_DHM_C`) is present, even when `MBEDTLS_USE_PSA_CRYPTO` is enabled.
