So a darkvision party, who refuse to bring torches or use Light, should still be getting disadvantage in dim light?

@JeremyECrawford Do characters with darkvision have disadv on perception in darkness since it's treated as dim light & lightly obscured?

If something is dim light, it follows the rules for dim light (PH, 183). This is even true of the dim light in the rule for darkvision. #DnD https://t.co/ituPIpRZvd

So my all darkvision party, who refuse to bring torches or use Light, should still be getting disadvantage? This changes everything.
