"I rarely find myself in need to use my.ini for clients".  Not me either
except for max_allowed_packet (what is implemented in both server and
client) that user want to set to INSERT table rows with photographs (.jpg's
typically) to a table.

And the 'mysql' command line client has a default max_allowed_packet of 1MB
(in the server it was raised to 4MB in MySQL 5.6 - and if I remember right
it is 8MB in recent MariaDB - but I belive the client setting is still 1MB
even in MySQL 5.6 - I have not checked though).

In contrast the C-API (both Oracle's and MariaDB's) has a defaut of 1GB
(not sure about other connectors - such as JAVA and .NET). But I am not
aware of any GUI client compiling/linking the connector with client
max_allowed_packet lowered from 1GB (the highest possible value the
protocol allows for currently).
