remove prefix from WE, what happens to prefix ?

[paulgirard]

I merged abc.com into fr.abc.com Then I changed my mind, go into fr.abc.com. Into the page list I find the new prefix : com.abc

I remove it.

Now to which WE this prefix belong to ? If I search into web entity list I can't find it. I had to reimport it to (re)create abc.com.

The prefix might have been silently merged into the TLD www.com web entity.

Maybe we should apply defautl web entity creation rule to prefix which are removed ?
