Pruning non-transaction data instead of pruning whole blocks?

The inquiry touches upon the concept of pruning witness data from transactions within a blockchain network, specifically questioning whether witness data, deemed not "required" for a transaction once its validity is confirmed, can be subsequently pruned from the node. This addresses a nuanced aspect of blockchain management and optimization, highlighting the importance of efficient data storage and the potential for reducing the amount of data nodes must retain over time. The question originates from a user named @cooltexture, who seeks to understand the feasibility and implications of removing witness data post-validation, suggesting an interest in how blockchain networks can be optimized for efficiency and scalability by potentially discarding redundant information.
