HL1 is part of the UBA, even if you, personally, don't like it. Two
implementations, opting to use HL1 one and the other not, can both
conform to the UBA.

There is no standard on whether HL1 should be applied or not for plain
text email clients.

Outlook employs a higher level protocol. It is "all paragraphs are LTR,
unless the user presses CTRL+RIGHT SHIFT, in which case all paragraphs
are RTL". It is a valid, standard conforming protocol, even if Eli
Zaretskii doesn't approve.

HL1 states the exact opposite. Last I checked (half an hour ago), it was
still part of the standard.
