Hard disagree. If there isn’t a mobile-first strategy it’s not even going to be “good enough” and nobody will use it.

I would rather have a solid simple program a year from now than a janky one today.

The Nostr protocol actually changes this dynamic because users aren't trapped within a specific app. A higher-quality app can take over the market, even if it arrives much later. "Being first" doesn't offer as much advantage, in an open protocol.
