Well, I would actually encourage the use of "bidded". It's an example of progress in the English language.
A progress towards increased clarity, and disambiguation. Current British usage of the verb "bid" is sullied by an ambiguity. The Present Tense "I bid " (now, today), isn't distinguished from the Past Tense "I bid" ( yesterday).
Of course, one might say this isn't a serious problem. We can usually guess which tense is meant, by the context in which the verb is used. Nevertheless, a clear verbal distinction would be better, as it does away with the need to guess.
Hence I think the distinction "I bid - I bidded" is a valuable advance towards clarity.
If anyone isn't convinced, consider the case of another short verb - "to fit". In British English, we clearly distinguish the Past Tense, by using "fitted".
But our American friends lamentably have yet to make this distinction. In American English, you'll see statements like:
"I bought a new dress last week - it fit perfectly!" To our advanced British eyes, doesn't that look gratingly wrong?
As wrong, I suggest, as "I bid yesterday" will soon seem. So let's welcome " I bidded" !
