Currently, brackets written with \left( generate syntax errors if no corresponding \right) command is used. bigl et al. should also generate syntax errors.
See for example
physikerwelt@a1 texvcjs % ./bin/texvcjs '\bigl( a'
+{\bigl (}a
physikerwelt@a1 texvcjs % ./bin/texvcjs '\big( a'
+{\big (}a
physikerwelt@a1 texvcjs % ./bin/texvcjs '\left( a'

[mediawiki/services/texvcjs@master] Convert (bB)igg?(l|r) from literals to left/right objects
Change 980006 abandoned by Physikerwelt:
[mediawiki/services/texvcjs@master] Convert (bB)igg?(l|r) from literals to left/right objects
Reason:
this is unfortunately incorrect, one can use \bigl without error but not \left. without error
Unfortunately, it is not that easy. bigl and bigr are normal operators they only adjust the spacing to the left or right, but don't define grouping terms
