Why not to have only 1 hook useTransactions with an optional parameter safeTxHash instead 2?

Why not to have only 1 hook useTransactions with an optional parameter safeTxHash instead 2?

You mean, combining useTransactions and useTransaction?
To me it's just more clear what the specific hooks do when having them separated. Because useTransactions returns only the executed transactions, while useTransaction can fetch a pending multisig transaction which is not executed yet -> so I see them as different use cases.
If we had them combined in one hook, I think it might be harder to understand how to use it (which params are needed, what does it return). But open to suggestions of course.
