Comment (by Shai Berger):
Replying to [comment:1 Adam Chainz]:
> An alternative to changing the default would be to have a system check
highly recommending READ-COMMITTED [...] "Warning: In Django 2.1 the
default tx_isolation will change..."
That may indeed be the way to go. Two issues arise:
1) We need to make sure which deprecations can happen when (WRT our
deprecation policies around LTSs)
2) It may be seen as annoying: "if you know that it's correct to use that
other level, why don't you just go and do it? why bug me?"
The big advantage is that it completely solves my 2nd backward-
compatibility issue.
