Don't you realise that discussion of whether right hand justification
is good or bad is irrelevant in designing systems for widespread use?
Some users think 'full' justification essential (and when using narrow
columns will require hyphenation to make it look reasonable), whereas
others will think the opposite and require ragged right justification.
(Personally I think it depends what type of document is being set).

So as a key criteria for good system design is meeting the user's
requirements, you have to offer all standard forms of justification,
and at least some form of hyphenation (Knuth's TeX does pretty well so
why can't you?)

It doesn't matter if YOU don't think the user ought to justify: if he/she
doesn't agree with you he/she will go elsewhere.
