Among all the methods I added to Data.Sequence, the most code-intensive are tails/inits and consDigitToTree/snocDigitToTree.
The second was more intensively used with some previous zipWith implementations that have since been replaced, but they add moderate speed improvements to the significant amount of already-bulky code for appending two sequences, and I can live with that on my conscience.
In the latest version of your patch, consDTree/snocDTree are defined using foldr/foldl, which expands to repeated consTree/snocTree. In that case, it would be simpler to go back to writing out the repeated consTree/snocTree.
