What wrong with do both as hard fork? Wouldn't segwit hard fork be better than soft fork?

I assume if hard fork for both then there is a need to allow legacy txs to be converted at a later date. ie. 10 years.

A soft fork is always better if possible because of the "danger of two competing blockchains", ~~and I don't see how a hard fork can solve the quadratic hashing problem here.~~ (edited, see below) But legacy transactions cannot be permitted in an unrestricted way after the 2MB activation like today, as Lauda correctly points out:

I don't see how 2 MB + Segwit would avoid the quadratic problem on it's own. It needs to have some constraints on native transactions in order to work.

So the "grace period" between the Segwit activation and the 2MB activation must be as long as possible (~1 year) to correctly evaluate the danger of "full block spam" (in this case "4 MB block spam"). Edit: And the 2 MB hard fork should contain also a restriction for legacy transactions. Maybe they can be prohibited and all people owning bitcoins on non-Segwit keys have to transfer them to Segwit addresses. But we don't have to do that already when the Segwit soft fork is activated (so we don't need a hard fork then), the 2 MB hard fork 1 year later would be early enough.

Regarding the possible 8 MB block spam, as I have already discussed in another thread, I would support going forward slower (first go to 1,5 MB/6 MB max. after a year and then to 2 MB after 1-2 years more if everything works right).

Can't do that.

However maybe...
On an isolated network with full blockchain - do a soft fork. If it works then make multi copies of the blockchain. Required a huge degree of trusted parties.

Do a hard fork as normal and everyone goes seggy.

Those who aren't aware would still be protected based on the multi copies of the blockchain.

Say 10 years time someone pops up and wonder where their bitcoins are. Trusted parties can use one of the multi copies of the blockchain. to allow the person to transfer his legacy coins to seggy hard fork blockchain.

Would that work?
