Keep in mind: Putin does do these things. Ukrainian children are separated from their families and placed with Russian families to be raised as Russians. That's genocide. Adult Ukrainians have reportedly also been deported and made to live as Russians on the other side of Russia, separate from other Ukrainians. There's plenty of talk in the Russian media that all Ukrainians believe Ukrainian is a valid ethnicity should be killed. And we've seen the result of massacres.
Sure, Putin doesn't do industrial scale murder of millions the way Hitler did, but as you point out, genocide is broader than that.
