Yes, this is a good point. As they say, they will be swapped at the edges by a few nodes. Not sure about the adoption otherwise, among institutions, let alone the plebs. Taro (or maybe CMYK, which was the working title early on, a play on the fact that it ripped off RGB) has been Lightning Labs main focus for a while now. Lightning Labs, whose implementation is LND makes up between 80% to 87% of network nodes, so at least the overwhelming majority of the network will be quite compatible with Taro.
Much of the network has been unhappy with Lightning Lab's priorities of dollarizing the undollar-ed with Taro, rather than focusing on Bolt 12 and interesting privacy maneuvers of splicing being developed with Blockstream's implementation of C-lightning.
