Is it correct that variables manipulatable by zmlocalconfig can universally be set either to "true" or "1" interchangeably, and to "false" or "0" interchangeably?

A number of these variables on our and some of our clients' older systems seem to use "true" and "false" instead of zeros and ones.

For example Bug 46264 – ClassNotFoundException in LDAP code when trying to find EasySSLSocketFactory talks about setting ssl_allow_untrusted_certs to "0" and "1" but on our hosting farm we see this is set to "true".
