You are attacking a straw man here. To use a period in an identifier,
you have to double-quote it; that's the same in SQL or \d.
regression=# create table "foo.bar" (f1 int);
CREATE TABLE
regression=# \d foo.bar
Did not find any relation named "foo.bar".
regression=# \d "foo.bar"
Table "public.foo.bar"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
f1 | integer | | |
According to a quick test, you did not manage to break that in v14.

I do not understand why you're even questioning that. The old
behavior had stood for a decade or two without complaints.
