What is Client Payload Data Limit for LWC?

Question

I was playing with LWC and was checking limits. I could not find what the max client-side payload limit like the way we had in Aura.

Aura had 1MB limit which was increased to 4MB recently. Anyone has idea whats client payload limit for lwc?

There's no specific mention of the limits on the documentation at least. Seems to be a candidate to get confirmation directly from Salesforce. — Jayant Das, Commented Feb 25, 2019 at 15:14
