Does SLP work with the default electron cash implementation?
Not yet. SLP in EC is in beta and they plan to merge it into the master in the next month. EC is also looking at adding it to mobile shortly after. Source: Devs in Telegram
What's the rollout plan for other wallets? Specifically a well trusted web wallet like blockchain.inf, coinbase or bitpays web wallet.
While I can SPV some will need a website.
I've only heard the rollout plan for EC. I assume other wallets will be quick to add it once usage picks up.
