It's not moralistic. It breaks assumptions built into the linking system, may pollute caches, and very likely isn't portable. What will happen is implementation-dependent. The behavior you get after cd can be surprising, and some systems may refuse relative paths outright.

Let me put it this way: Putting . and .. in PATH also causes real issues in a shell. These paths are supposed to be absolute. When they're not, the cache the shell uses for tab completion may get confused, as now needs to dump it every time you cd and may not do so. A false positive or negative in tab completion is just annoying, in loading libraries it may actually break something.

Just because you can do something doesn't mean it will work the way you think it will, and just because you can do something doesn't make it a smart idea.

systemd-path

SYSTEMD-PATH(1) 						   systemd-path 						   SYSTEMD-PATH(1)

NAME

       systemd-path - List and query system and user paths

SYNOPSIS

       systemd-path [OPTIONS...] [NAME...]

DESCRIPTION

       systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for
       querying.

       When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
       with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
       to a list of colon-separated search paths, in their order of precedence.

OPTIONS

       The following options are understood:

       --suffix=
	   The printed paths are suffixed by the specified string.

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
