I'm certainly not technical enough to know how big this is, but I've seen enough posts lately about drive chains to sense that I should try and understand more about what's going on.

For those in the know: is the debate about drive chains in any way comparable to the block size debate of 2016/17 in terms of scale, importance, potential "war", etc?

Or is this just normal core devs debating that I'm just more aware of this time round? I see (for example), that @petertodd doesn't like luke's approach. But is this cause for concern, or just healthy debate?

Genuinely just curios to know.
