Ishan Chattopadhyaya commented on SOLR-14768:
---------------------------------------------

bq. Today Ishan Chattopadhyaya (j...@apache.org) finally noticed our Jira entry 
and asked me for patches.

I didn't exactly ask you, but expressed the general sentiment that this is an 
area where contributions will be appreciated.

bq. A second free suggestion 
bq.   A last freebee

Thanks for your "free" suggestions to improve a free (and open source) project.

bq. in fact a chore for the code maintainers rather than end users. There

bq. we cannot be expected to become deeply immersed in this dense material. 
That chore for those responsible people. Thus can we escalate matters to those 
folks and see if we can rectify the problem.

Please keep in mind that Apache Solr is a search engine, and all committers for 
the project are volunteers (like you) working as hard as possible to improve 
the project. Part of the reason why we wish to deprecate Tika/Solr 
Cell/Extraction is that this is one of the non-essential functionalities for 
our project which has not received the level and quality of support that we 
strive hard to provide for the rest of the project. Thank you for your 
suggestions, they make sense. We realize the importance of this functionality 
and also wish to continue supporting this functionality via non-core packages 
(either official Solr packages or community supported packages) going forward. 
Having said that, we also wish to help resolve all outstanding issues (like 
this) that have been caused inadvertently.

FYI David, [~tallison].
