Always allowed qualifiers?

There are certain qualifiers, namely sourcing circumstances (P1480) and nature of statement (P5102), that ought to be allowed on all statements, regardless of the presence of this constraint. Is there 1) a technical means of achieving that, and 2) support for implementing that? Swpb (talk) 18:55, 6 August 2019 (UTC)

I agree, but more specifically with reason for deprecated rank (P2241) and reason for preferred rank (P7452) RPI2026F1 (talk) 22:59, 8 March 2023 (UTC)

Prohibited qualifier?

Can we have something like "prohibited qualifiers constraint"? While editing NDL Authority ID (P349), I want to specify replacement property (P6824) for some dis-allowed qualifiers. Or is it possible? fryed-peach (talk) 15:55, 6 April 2024 (UTC)
