It definitely can benefit from more people working on it. We need an economically sound network for Nostr to survive.
Nostr relays, micro-services, etc.. can all benefit from a single UI to manage them and opt-in renew them or top up credits.
We will benefit from less payment friction - but the only caution is around we need to make what people are paying for very obvious to prevent scams or accidents. Financial privacy is important, but a functional POC first would suffice.
