Use for application items?

Examples:

• HTTPie (Q68453830)protocol (P2700)HTTP (Q8777)
• FileZilla (Q300662)protocol (P2700)File Transfer Protocol (Q42283)
• nheko (Q61754440)protocol (P2700)Matrix (Q22906785)

To state a application can "speak" this protocol. Currently implementation of (P4428) is sometimes used for this purpose, but it does not feel quite right. --Haansn08 (talk) 20:47, 30 July 2020 (UTC)

•  Support Much better than Conversations (Q17122691)uses (P2283)XMPP (Q188951) and Signal (Q19718090)has part(s) (P527)Signal Protocol (Q27031176). There is nothing wrong with implementation of (P4428) but protocol (P2700) is more specific and natural. —Dexxor (talk) 13:08, 31 July 2020 (UTC)
