Optionally avoid multiple n/w calls when original bidder and alias bidder configured together.

Scenario

A bidder with the name BidderA has an alias BidderAAA.
This bidder accepts only one parameter say publisherId
On the SSP server-side of the bidder, they know for a given publisherId, whether the SSP is enabled as BidderA or BidderAAA or both.
So based on the publisherId, the server-side can respond with separate arrays of bids that can be submitted per alias.
Hence the bidder does not need to make a separate network call per alias from the publisher page.
What is the ideal way this bidder should submit the bids in Prebid JS?
Is it fine if the bidder sets the bid.bidderName based on its own logic and then submits the bid to the Prebid core logic?
I found that this way works fine.

Please note that this approach may not work for each bidder based on their own implementation, but if it works for a bidder then we can allow it.

This is very interesting, we call IX adapter and IX roundel alias for example. @ix-prebid-development . If there is a better way, it could be a significant overhead savings.

Discussed in committee. We interpret this request as a rules question: should Prebid.js validate biddercodes returned by bid adapters?

Question: is the intention here to limit bid responses to pre-declared aliases of the adapter, or is the idea that bid adapters should be able to inject responses from any biddercode?
