I initially added this requirement in 74f0d0ff2529aed1ce07bb2409ea204c9cadd99c with the following comment:
I had to require pear/pear-core-minimal on top of pear/pear_exception because there is no transitive dependency. I have opened pear/PEAR_Exception#8
It seems pear/pear-core-minimal was actually not necessary if we don't use
PEAR_Error in our codebase.
That will be one less package required.
