I'm not well versed in gacha, but the ones I played genshin and HSR certainly don't work that way. As a twintail collector it took more than 3 years until I could do a full twintails clear that could work (and it was because nilou happened to restrictively want such characters, and unfortunately she has been phased out already due to powercreep). Hu Tao seriously needed xingqiu (C6) and even now you need either him or yelan (and ideally zhongli at the time, only many years later appearing options with plunge team that also has it's needs and citlali). HSR is just worse in general than both by a large margin.

And the more characters are released the more synergies it will appear. Lupa will work with any fusion character that wants fusion stats, and is fairly powercreep safe because they can't powercreep stats without making echo farming irrelevant. The other supports like roccia, brant and cantarella are getting more options, as does most dps outside of carthetyia and zani for now which are the only bad case if they don't follow up with more dot characters.
