Dbdriver files being deleted

One thing that has puzzled me thus far is why I only saw the option for the
jTDS driver in the datasource type combo, even though I placed the jTDS,
MSSQL, PostgreSQL, and MySQL extensions in the deploy folder. Then I
noticed this in the server output:

file:…app\WEB-INF\lucee\context\admin\dbdriver\MySQL.cfc
Thu Oct 22 13:26:09 CDT 2015-194 delete
file:…app\WEB-INF\lucee\context\admin\dbdriver\MSSQL.cfc
Thu Oct 22 13:26:10 CDT 2015-755 delete
file:…app\WEB-INF\lucee\context\admin\dbdriver\PostgreSql.cfc

Seems like a bug - is a reason why it is deleting the dbdriver files while
deploying these .lex files?

I should clarify - I have experienced this Lucee 5, starting with .65-BETA
through .98-SNAPSHOT.On Thursday, October 22, 2015 at 1:33:09 PM UTC-5, Jesse Shaffer wrote:
