You are not allowed to put relative paths in LD_LIBRARY_PATH. That is a very insecure thing to do.

for further communications please note explicitly that your argument is pure moralistic and not a technical necessity.

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.
