I use it. It's the only way (I know of) to get Amazon to do support for
kernel issues. Even as compared to Redhat, they will take a look at live
crashed instances having problems...nobody else has that access. And as far
as I know, they use it too, and perform quality assurance on it on their
platform. Solution or workaround for that class of bugs is not particularly
portable to other Linux distributions.

In general, I have found Amazon Linux an easier target in most respects:
one can drop workarounds to cope with the ancientness of CentOS6. Notably,
access to new libraries (e.g. libcurl) allow easier updates to libraries
like gdal or geos with fewer patches to cope with old compilers (by
installing gcc64-c++). It also tends to have new kernels that are lightly
modified to deal with specific issues (per changelog).

Amazon Linux however, different, and makes releases that move rather
quickly. It's rather closer to Fedora in a way.

Sometimes, as with programming languages, they are fairly fastidious at
separating out old versions of packages (e.g. pip-3.4, pip-3.5, pip-3.6 for
Python), and for better or worse, sometimes, in cases like gcc, libevent,
libcurl, or boost, they'll Just Upgrade.

So, in this case, you can fix the build by dropping the "2" in the package
name. They seem to have relegated libevent 1.4 to "compat-libevent"
