Take a look at the announcement of Pi-hole support for ABP lists.
Pi-hole only supports the "Blocking by domain name" syntax you mention, which blocks domains plus their wildcard subdomains, while ABP itself can support other syntaxes relevant to browser-based filtering. So Pi-hole will block domains from hosts lists (such as the list you mention), and domains (and their wildcard subdomains) from ABP lists where there are entries in that single supported format.
Going the other way doesn't really work, since hosts entries would have to be turned into something that ABP interprets as a non-wildcard domain based entry, but ABP doesn't have such an interpretation since it works at the browser level. Turning them into wildcard entries means too much would be blocked by ABP, and turning them into exact address entries means too little would be blocked by ABP when a web-based pathname is present.
It's not Pi-hole's place really to try and second-guess this or curate such lists. That said, if you decide on which compromise you want to make, you can turn your hosts lists into ABP lists using a bash script. When run against a hosts list it would write out the desired ABP list.
