Multiple DVB-T receivers and dump1090

Is this (still) a supported configuration for MLAT? Mine has started throwing this warning when I feed two dongles from the same remote Pi into a local dump1090:

11/03/2017 21:51:58 mlat-client(23251): Warning: the timestamps provided by your receiver do not seem to be self-consistent. This can happen if you feed data from multiple receivers to a single mlat-client, which is not supported; use a separate mlat-client for each receiver.

Feeding more than one receiver output to a single piaware/mlat has never been a supported configuration. You need a separate piaware for each receiver (you can combine the outputs for display, just don’t feed the combined data to a single piaware)
