No, the need for seeing WoT before updating is resolved by the fix you made today, assuming that was a general fix and didn't only apply to Wisp.
I'm talking about having WoT visible on the app info page simply because people viewing that page may find the information useful. If they have never installed the app before, they might use it as part of their decision-making process, or they may just want to see if the publisher is reputable before adding the app to one of their stacks, since others might view that as their endorsement.
Only having that information visible when a user hits "Install" means that users have mostly already made the decision that they're going to install the app before information that may have changed their mind is presented, and it means the information isn't visible at all for users who already have the app installed, but still may find WoT details useful for other reasons.
"Oh, my buddy Derek follows this dev? He probably uses this app too so I'll reach out to see how he likes it compared to X similar app."
