This is in the interest of who the board represents, not you though. If you’re willing to listen to the board you would anyway? It’s reasonable to grant this power to the board as part of a an incoming shareholders’ ask, but would you volunteer it?
Shareholders Resolutions trump board resolutions too, so you’d need to factor that in.
You need a business to shield you from personal liability. You may be taking on personal liability early on in your project, more than you may realise. You have to balance this with bringing in a cofounder as you may accidentally create a tax burden for a late founding shareholder - in the UK anyway.
