Comment (by Nikolay Tretyak):
Yes, {{{Charfield}}} uses {{{''}}} as an empty value. But if you use
{{{filter(charfield=None)}}} it will produce {{{IS NULL}}} sql, not {{{=
''}}}. And this behavior is clear. So, why should we transform
{{{filter(jsonfield=None)}}} to {{{= 'null'}}}?
I think that the majority of JSONField users want to check if the
{{{jsonfield__key}}} is {{{'null'}}}. But are there any use cases when
they want to store just {{{'null'}}} in the whole field instead of SQL
{{{NULL}}}?
