Ok,
1) you love bikes
2) you know the rule is N+1
I should not have to go farther, but
Gravel bike is a very practical solution overall, depending on which one you pick you can handle roads, gravel, trails, bike packing, commutting
In full disclosure....I really like steel (I don't hate aluminum or carbon, but like steel)
Good steel frames are smooth, ride well, look good, are durable
not sure what your budget is but here are a bunch of steel gravel that cover a range of looks and features some are complete bikes and some are frames

you know you want one....just go for it
of course another option is custom
this is not a "gravel bike" but does fit 32mm tires and I do take it on some gravel (and because there are not enough pics of bike in the general thread)
Dave Kirk custom (look into what he call a Montana Road bike)
