All alternatives in the FAQ (portable or not) are less readable than a simple pipe. They are all more verbose and introduce an extra level of nesting when you have only one "command". They all need to be read "backwards" with respect to the execution flow. If you want to keep your code readable, they practically all force you to define a function for "commands" as soon as you have more than a few commands. Every entry in an FAQ is by mere definition a problem that many people wast... spend time on. It is admittedly not a question of life or death but some other shells apparently have it so why not bash? Just asking.
