This is slightly related to #2559 and #2529. IMO there is no easy fix because even if you grant some initial values, there is nothing forcing the endpoint to use the first available unidirectional streams for control streams. The temptation is to set these transport limits quite high in order to just avoid the issue but that prevents the sending endpoint from overwhelming the receiver with a lot of data. An alternative is to set a conservative value for `initial_max_stream_data_uni`, say 8 bytes. This would allow the sender to open a uni stream with a type, the receiver can use this to determine if/how to grant further credits.
