The Prebid Board would like the default to be "no cache", so that would change this default to false, right?

In your e-mail you said the board wanted the ability to "opt-out". If I changed the default to false wouldn't that be "opt-in" in regards to bid caching?

My recollection of the board discussion was publishers would have to opt-in and we'd disable by default

believe we decided to add the flag as the 1st step, then as a 2nd step making it off by default (breaking change).

@mkendall07 that's what I recall as well, which is how it is implemented now. Also, switching it to off will require some effort more than just changing that constant. Since many tests related to targeting assume bid caching, they will have to be updated to behave appropriately.
@bretg let me know if this is okay as is or if we want to further discuss switching the default.

I updated the docs PR with a warning that the default will be changing in the coming releases.

Then we ship it as a 2.0. We are not making breaking changes without major version changes period.

So sounds like this is the plan, right?
1.x - leave bid-caching on by default, but add a config flag that will allow a publisher to turn it off
2.0 - turn bid-caching off by default and let pubs turn it on with a config flag.

correct, thanks. @bretg if you have reason to push this out sooner than an expected release for 2.0, we should talk about how to handle. I.E if we make it the only change in 2.0 that's probably OK but it creates additional overhead to support legacy for 30 days per our policy (vs releasing a bigger 2.0 release)

The board wants this change done 3 months ago.
So if we want to increment the version as a result of this change, so be it. Let's plan for a 2.0 by the end of the month then?
