Worth noting that the transaction sponsors design is no worse an
offender on this count than, say, CPFP is, provided we adopt the change
that sponsored txids are required to be included in the current block
*or* prior blocks. (The original proposal allowed current block only).
In other words, the sponsored txids are just "virtual inputs" to the
sponsor transaction.
This is a much different case than e.g. transaction expiry based on
wall-clock time or block height, which I agree complicates reorgs
significantly.
