I've always found the page.$, page.$$ (and their eval and frame etc. counterparts) weird as function names. Mainly for the fact that $ really is no English word giving any information as to what they do. I believe this might come from jQuery, but I have no idea why Playwright would need to follow that style.

Now that e.g. page.waitForSelector() exists, is there e.g. any need at all for page.$? I realize there is no equivalent for page.$$ (and maybe the evals, although element.innerHtml() etc. now exists that can be done outside of an eval.)
