A Taproot-native (re-)bindable transaction bundle proposal

The inquiry centers around the perceived challenges or less successful applications anticipated by the creators of Taproot, a notable development in the Bitcoin protocol, several years post its activation. The person raising the question expresses unawareness of any specific expectations or claims made by Taproot's developers regarding its utility and adoption trajectory over time. This query implicitly seeks clarification on whether there have been any voiced concerns or predictions about areas where Taproot might not perform as hoped or meet its full potential. The individual is keen on ensuring that their understanding is based on actual statements from the developers rather than assumptions or misinterpretations possibly circulated within discussions. This reflection underscores a desire for accuracy and direct insight into the developers' perspectives on Taproot's long-term integration and effectiveness within the Bitcoin ecosystem.
