WALLET tells:

Output descriptors are part of a developing standard for Recovery that WALLET_PROVIDER intends to support and is helping grow. Since the standard is in a very early stage, the list above includes some non-standard elements.
When descriptors reach a more mature stage, youʼll be able to take your funds from one wallet to another with complete independence. WALLET_PROVIDER believes this freedom is at the core of Bitcoinʼs promise, and is working towards that goal.


user208: The "musig" descriptor function has not been standardized.
These descriptors also don't seem to contain valid key expressions (which need to be hex pubkeys, hex x-only pubkeys, xpubs, xprvs, or WIF keys, possibly combined with origin information or derivation paths).
Also, descriptors currently don't permit spaces inside.
