The upstream is going to do this with a precomputed 2048 bit DH parameter.  To keep this interim fix simple and not a performance degradation, I went with a run-time generated 1024 bit.  Sites which wish to use 2048 run time can override the default in their configuration.  Likewise, when 8.15.2 is imported, sites that prefer not to use a precomputed DH parameter can create their own by overriding the default to use a run-time or their own precomputed (but "unique") using a DH parameter file on the local file system.
