I'd love a native Proton app/feature for outbound connections from my home router, with four independent options I can turn on or off separately:

Access my own network – securely reach my home devices (NAS, cameras, etc.) from anywhere, without opening any inbound ports on my router/firewall.

Share my bandwidth – let my home connection help Proton's network (extra exit capacity), fully opt-in.

Hairpin my mobile traffic through home – route my phone's traffic back through my home internet connection when I'm out, so it looks like I'm browsing from home.

VPN out specific LAN devices – pick one or more devices on my home network and route just their traffic out through Proton, without affecting the rest of the network.

Each option should work on its own — I might want just #1 and #3, or just #4, without needing the others active. Since Proton already has the WireGuard backend and account system, this feels like a natural feature to build rather than a new product.
