Q:

Why is . not in the path by default?

A:

More than a security risk, having '.' in the PATH make almost impossible to make it sure that the execution of any command acts as intended. Think about running a command like 'zip' in a huge directory containing thousand of files with random names. The possibility that one of them is actually named 'zip' is not negligible and would lead to an error which is very difficult to understand (actually the file should be executable, which, however, might happen). 
In particular this is true when writing scripts that keep the PATH variable of the user. A good written script should deal with all corner cases (like filenames with spaces in them or starting with '-'). But it is impractical to prevent a file in the current directory being executed instead of a system command...

In our case I often run ../bin/cin from inside 'cinelerra' folder in CinGG source tree or you can call it from root of this tree:

 
root at slax:/dev/shm/tmp/cinelerra-goodguy-20210119/cinelerra-5.1/cinelerra# cd ../
root at slax:/dev/shm/tmp/cinelerra-goodguy-20210119/cinelerra-5.1# bin/cin
