To an extent. I mean there's that relatively new idea of "gravel bike" but probably not that many more. And I think marketing has led that, it's not necessarily that people needed a defined machine specifically for very light, slightly quickish off-road circumstances, but bike companies love telling people they do. Can't blame them I guess, if I were in the bike selling business I'd be doing the same.
I think if you own a good tourer with decent tyres and a good rack, it's easy to think you've got the bike that does the most, they do cover a lot of the cycling "Venn diagram". Certainly once I got a tourer a couple of years ago I got rid of two whole other bikes (a carbon road bike and a shopping hybrid) as it did both their jobs.
I'm not quite convinced there's that many more defined, specific bike types now anyway. There's road, MTB, hybrid for sure, then really specialised stuff like those big Bakfiet cargo things, tandems, everything else is really just a slight variation on one of those former main groups. A gravel bike for example is really just a road bike adapted to wear more sensible footwear.
