Sure. But what, besides sorting, are you thinking of?
Are you thinking of sorting using a composition of
predicates? Sure, you could skip that.
With Bookmark+ you can compose predicates, but
nothing obliges you to.

Each of the predefined sort orders in Bookmark+ in
fact uses a single predicate, not a composition.
You could incorporate some of the same, or similar,
predicates in `bookmark.el'.
The default value of `bmkp-sort-comparer' is,
however, a composition:
((bmkp-info-node-name-cp
bmkp-url-cp bmkp-gnus-cp
bmkp-local-file-type-cp
bmkp-handler-cp)
bmkp-alpha-p)
That sorts by bookmark _type_, for some predefined
types, and for other types it falls back to sorting
alphabetically by bookmark name. It corresponds to
command `bmkp-bmenu-sort-by-bookmark-type', which
is bound to `s k' in the bookmark display list
("k" suggests bookmark "k"ind; `s t' is taken by
sorting "t"agged bookmarks before untagged ones).
But your option could support only a single pred.
A comment even suggests this:
;; An alternative default value: `bmkp-alpha-p'
And as the `bmkp-sort-comparer' doc I sent says,
You can also convert a PRED-type predicate (which
returns (t), (nil), or nil) into an ordinary predicate,
by using function `bmkp-make-plain-predicate'. That
lets you reuse elsewhere, as ordinary predicates, any
PRED-type predicates you define.
> And for users that need more there is Bookmark+
If bookmark.el provides something then Bookmark+
need not provide it. ;-) Bookmark+ exists because
the features it provides weren't wanted by Emacs.
