Could I ask what the use case is for i386 support? I know
that the pointers are smaller but memory is cheap. Is this
a speed or a hardware or a can it be done goal?<br>

<div>There are several items I see i686 support being
needed:</div>
<div><br>
</div>
<div>1) Memory is not cheap in cloud and hosted
environments. Especially in cloud where you might be
firing up a thousand hosts at a time.</div>
<div>2) Multiple Virtual Machines don't do well in the
transition from 32 bit to 64 bit in that their memory
usage doesn't go up by *2 but can be ^2 depending on the
workload. Python is a perfect example of this but there
are cases in java and other 'virtual machine' environments
where it happens.</div>
<div>3) As nice as having i686 compat libraries are for some
commercial apps you end up needing a lot more than what is
provided by the OS. This really comes up when you have to
run a mixed set of commercial binaries that need something
that only EL7 provides but also needs stuff that EL6 had.
Thus you end up needing i686 everything.</div>

for what is worth I have some _expensive_ EDA tools from Incisive
which bundle 64bit binaries in the supposedly 32bit toolchain as
well as an IBM tool which requires a 32bit OS lib in its _64_bit
toolchain....<br>
