I think the way electron apps abound when there are possibly better alternatives is similar to the way markdown abounds in spite of other better 'lightweight' markup alternatives.. after years of using markdown, I've migrated to asciidoc and couldn't be happier that I don't have to rely on custom extensions..

I guess it's a mindshare thing and a learning curve thing.. I guess markdown is good enough for the vast majority of cases.. but when it isn't, it becomes a pita..
