Comment (by Mariusz Felisiak):
I've checked MySQL 8.0.13 release notes once more time:
''"MySQL now supports use of expressions as default values **in data type
specifications**. This includes the use of expressions as default values
for the BLOB, TEXT, GEOMETRY, and JSON data types, which previously could
not be assigned default values at all. For details, see Data Type Default
Values."''
it looks that MySQL support is limited to the `ADD COLUMN` statement. We
should revert 6b16c91157512587017e9178d066ed1a683e7795 and close #30712 as
wontfix.
