Shouldn't tooltips be a native Figma feature?

Decades ago when prototyping interfaces I would just use HTML prototypes, which made tooltips super easy to prototype. 

Decades later with Figma - which is an excellent design and prototyping tool don’t get me wrong - adding tooltips to one’s prototype, is incredibly painstaking. 

It would be so much easier if Figma just added a field for each layer called “tooltip”, which, when hovered over in prototype mode, would display the tooltip after a number of milliseconds (which could be customized as a bonus feature). 

This would make Figma prototypes tooltip-friendly in such an easy way. 

And from a designer-developer handoff perspective,  it would be great if Figma prototypes had a toggle to enable text selection in the prototype. That way the developer would just run the prototype, get the tooltip in context, and copy its text.
