I also consider that we should provide info so that we can properly map the
Boolean type according to the expected SQL type.
Especially since we have revamped the support for Stored procedures and

So this comes from the fact that Oracle does not support a BOOLEAN
datatype. Well kind of. It does not support a BOOLEAN datatype in its
"SQL engine". However, in PL/SQL it does in fact support a BOOLEAN
datatype. Which comes into play when we talk about calling functions and
procedures: the arguments and returns can in fact be a BOOLEAN.
As far as I know, Oracle is the only database with this type of
inconsistency in its type system. But the question is whether we want to
pass along some kind of information regarding the context (SQL v function v
procedure) to the Dialect#remapSqlTypeDescriptor.
You can look at https://hibernate.atlassian.net/browse/HHH-11141
illustration of how this impacts applications. And if you look through the
comments you can see the kind-of-crazy workaround needed.
