Review Comment:
Gson only has a single dependancy (Junit) so I would not consider it too
large
https://central.sonatype.com/artifact/com.google.code.gson/gson/2.10.1/overview
with a download size of only 12kb.
I did investigate other parsers including the one you linked. All of those
that I came across are either no longer maintained which includes minimal-json
or have very little usage. Additionally, because they are no longer maintained
they are not suitable for java 9 modules.
