Why would you prefer your own formatting style over a PG house style?
Its not *my* formatting style. It is an attempt to try to honestly record in a reasonable amount of reasonably portable effort the formatting style of the original author/publishing house. Because formatting has meaning. And what you are calling a "PG house style" is inevitably a "house lack of style" because the techno-nerds who foist these things on the world are inevitably the people who are the most tone-dead to the issue of taste, because if they had any taste they wouldn't be doing this stuff in the first place. What you-all are ignoring is the PG rules against blind-formatting of HTML, because blind-formatting of HTML makes *no* contribution to the world, and that is what you are doing: you are foisting blind-formatting of HTML on the world via an intermediate dumb-down language, rather than taking a good honest look at, and trying to be responsive to, what the original author wrote and the original publisher published. And frankly feedbooks and the lot have been doing what you propose for many years already, and have been doing it much better.
