Yes, I guess the quicker filter exhaustion must be the reason why
bitcoinj doesn't make use of outpoints in filters for standard
transactions. I'll look into if I can change that.

To Christian's point about privacy, I'll take this opportunity to

identify address clusters via the bloom filters in one of his publications.
By reducing the false positives when matching you can get very detailed
clusters. Then again we know that bloom filters aren't good for privacy
anyway,
As I understand it, the plan is to deprecated and remove BIP37 entirely once
BIP158 is implemented and deployed.
In the meantime, Bitcoin Knots supports the MSG_FILTERED_WITNESS_BLOCK
extension to download witness data. (Note that light clients currently have no
way to verify the witness data
Why not add the outpoints owned by the wallet to the filter and watch for
those instead of elements in the input script or witness data?

Bitcoin Core is not an identity that can be „willing to extend“ (or
