When we compare xendit's php library with doku or midtrans here:
https://github.com/PTNUSASATUINTIARTHA-DOKU/jokul-php-library
https://github.com/Midtrans/midtrans-php

We have many disadvantage compared to them:
-) very huge filesize (1MB zipped with all composer required library), doku only <10kb, midtrans only <30kb (core library). So currently we are the most bloated, maybe we can make it modular so dev can include only the feature they need. Reduced complexity will make this library more easier to mantain.
-) Other library doesnt force to use composer to install it. They work out of the box without any need for other dependency.

Even our official xendit woocommerce plugin dont want to use this library, they build their own. If our own developer dont want to use this library, do you think other developer will use this? Just let it seep inside our head for a day.

Most developer when look how complicated this library compared with the other library for the same category will stay away from using this library.
