Santisima Trinidad and the limits of repeated rebuilding

Is Santisima Trinidad a warning about ambition exceeding reality?

More precisely, it warns that an engineering change can be possible without being wise.

The lesson drawn from Santisima Trinidad is that technical feasibility does not establish whether a modification is sensible. Repeated work on an existing ship can become less attractive than building a replacement. A new hull is offered as the preferable alternative in this case, without a detailed comparison of costs.
