There is no generic MHTML generation across browsers yet, but you can still opt into using raw CDP as you do in Puppeteer:

'use strict';
const pw = require('playwright');
const fs = require('fs');

(async () => {
  const browser = await pw.chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage('https://en.wikipedia.org/wiki/MHTML');
  // There is no generic mhtml functionality in WebKit / Firefox atm.
  // Chromium-specific CDP accessor is now on the Browser-level.
  const cdp = await browser.pageTarget(page).createCDPSession();
  const { data } = await cdp.send('Page.captureSnapshot', { format: 'mhtml' });
  fs.writeFileSync('page.mhtml', data);
  await browser.close();
})();

Closing this for now. Note that it is unlikely that we can make it a part of the cross-browser API due to the lack of MHTML in Firefox. But if you have ideas on how this could be achieved cross-browser yourself, please let us know!
