Why does XMR.TO not support BCH and BTCP?

Why does XMR.TO not support BCH and BTCP? This question came to my mind earlier today. And I really had difficulties to find an answer. I mean, XMR.TO was created by the Monero community to enable easy extremely anonymous bitcoin payments for everybody. This is a very valuably contribution to the cryptocurrency space. But is the value created not even bigger if anonymous transactions are also enabled for other cryptocurrencies like BCH and BTCP?
BTCP support is useful until shielded transactions are as easily usable in BTCP as a mymonero transaction.
BCH support is useful because this guarantees being able to transact anonymously peer-to-peer at a very low transaction cost. Because the low transaction cost is the one commitment of the BCH fork, right? So it's guaranteed.

So ask yourself. Why would the monero community not protest against the developers' decision not to support BCH at that point. Double negations I know.
So why would the protest if the developers decided to actually allow BCH conversions?

I really think the just would not protest at all. Because to dismiss BCH just because I personally dislike it despite the fact that BCH support would increase monero adoption. This only makes sense if the monero consenus is: Ultimately the only purpose of Monero is the adoption of BTC. This is the definition of BTC maximalism.
Therefore the Monero consensus is BTC maximalism.
